A solution of (S)-2,2-dimethyl-4-(1-methyl-2-phenyl-vinyl)-oxazolidine-3-carboxylic acid tert-butyl ester (250 mg) in 4M HCl in dioxane (2 ml) was stirred at r.t. overnight. The reaction mixture was concentrated. The crude product was purified by column chromatography (silica gel; gradient: CH2Cl2->CH2Cl2/MeOH 9:1) to give (S)-2-amino-3-methyl-4-phenyl-but-3-en-1-ol (122 mg, 87%) as light yellow oil. MS (ISP): 177.9 ([M+H]+))
